Stress is a leading culprit in aging, so one way to slow the process is to reframe challenges in a less stressful light.

Last week during the second inauguration of President Barack Obama, I was noticing how our president had aged these past four years. His dark hair has been taken over by gray, the wrinkles a bit deeper in the brow.

I have seen this "presidential aging process" before. President Bill Clinton seemed to go from a vibrant young man at the start of his presidency to an elder statesman by the end of the 1990s. And this process is not reserved for Democrats. Republican President Ronald Reagan looked as if he aged 20 years during his eight-year tenure.
